Feasibility study to assess a novel combination of cytotoxic agents, docetaxel and oxaliplatin, as first-line therapy in the treatment of ovarian cancer and the impact of angiogenesis inhibition for the progression and prognosis of ovarian cancer by concurrent addition of bevacizumab (Avastin®).

A Pilot Phase II Study Evaluating the Combination of Oxaliplatin and Docetaxel With Bevacizumab as First Line Therapy in Patients With FIGO Stage IB-IV Epithelial Ovarian, Primary Peritoneal or Fallopian Tube Carcinoma

Tumor assessments were performed by Computed tomography (CT) and Magnetic Resonance Imaging (MRI) to evaluate disease progression based on Gynecologic Oncology Group (GOG) Response Evaluation Criteria in Solid Tumors (RECIST).

Disease progression was recorded as any one of the following:

appearance of a new lesion

symptomatic deterioration

progression of target or nontarget lesions

death

Participants who did not die or show show disease progression achieved PFS. PFS rate is the percent of participants who achieved PFS.

Median Time to Progression-free Survival (PFS) [ Time Frame: up to approximately 1300 days following treatment initiation ] [ Designated as safety issue: No ]

Time to PFS was the interval from the date of registration to the earliest date of disease progression or death, whichever occurred first.

Time of PFS was censored

on the last available tumor assessment date for participants leaving the study prior to disease progression or death; and also for participants requiring off-study medication or additional debulking surgery (where assessment date used was the one prior to off-study medication or surgery),

at Day 1, for living participants with no post-baseline tumor assessments.

Participants with Recurrence-free survival (RFS) were participants with a non-measurable disease at baseline, who had not achieved disease progression nor had died.

Disease progression included the following:

the appearance of a new lesion

symptomatic deterioration

progression of non-target lesions

a predefined serum CA 125 increase.

RFS rate was the percent of participants in the non-measurable disease subgroup who achieved RFS.

Median Time to Recurrence-free Survival (RFS) in Participants With Non-measurable Disease at Baseline [ Time Frame: up to approximately 1500 days following treatment initiation ] [ Designated as safety issue: No ]

The time to RFS was programmatically defined as the interval from the date of registration to the earliest date of disease progression or death, whichever occurred first.

Participants were

censored on the last available CA 125 biomarker blood draw date if

left the study prior to disease progression or death

they received off-study anti-tumor medication

underwent debulking surgery

censored at Day 1 if they were alive had no post baseline CA 125 biomarker blood draw.

A CA-125 response was considered at least a 50% reduction in the level of the biomarker, CA-125, from a pretreatment level, which was confirmed and maintained for at least 28 days.

The overall CA-125 biomarker response rate was defined as the number of participants in the measurable disease subgroup who met the above criteria at least once within the study treatment period +21 days, divided by the number of evaluable participants in the disease subgroup.

Overall Survival Rate [ Time Frame: up to up to approximately 1700 days after treatment initiation ] [ Designated as safety issue: No ]

Survival was the observed length of life from entry into the study to death or the date of last contact.

The overall survival rate (percentage of participants showing survival) at 12 and 24-months is reported here.

Median Overall Survival Time [ Time Frame: up to approximately 1700 days after treatment initiation ] [ Designated as safety issue: No ]

Survival was the observed length of life from entry into the study to death or the date of last contact.

The median overall survival time was estimated using Kaplan-Meier Curve.

Participants with International Federation of Gynecology and Obstetrics (FIGO) stage IB through IV ovarian, primary peritoneal, or fallopian tube carcinoma treated with Oxaliplatin, Docetaxel, and Bevacizumab - 28 days after initial surgery

Drug: Bevacizumab (Avastin®)

15 mg/kg bevacizumab administered intravenously (IV) over 30 to 90 minutes on Day 1 of every 3 week cycle for 12 months or until disease progression or unacceptable toxicity

Drug: Docetaxel (Taxotere®)

75 mg/m^2 docetaxel was administered IV over 1 hour on Day 1 of every 3 week cycle for 6 cycles or until disease progression or unacceptable toxicity

Drug: Oxaliplatin (Eloxatin®)

85 mg/m^2 Oxaliplatin was administered IV over 2 hours on Day 1 of every 3 week cycle for 6 cycles or until disease progression or unacceptable toxicity

Detailed Description:

Participants were

administered study medication approximately 28 days after initial surgery for ovarian cancer

received the study treatment regimen of up to one year unless there was disease progression, unacceptable toxicity, death, participant refusal, or treatment delay beyond the time frame permitted for each treatment

Participants were followed for survival for a minimum 3 years from the date of enrollment

Participant must have adequate urine protein/creatinine reaction (UPC) of <1.0;

Participant must have adequate neurologic function

Hepatic function: Total Bilirubin ≤ ULN; AST and ALT and Alkaline Phosphatase must be within the range allowing for eligibility. In determining eligibility the more abnormal of the two values (AST or ALT) should be used.

Blood Coagulation parameters: PT such that international normalized ratio (INR) is < 1.5 (or an in-range INR, usually between 2 and 3, if a participant is on stable dose of therapeutic Warfarin or low molecular weight heparin) and a PTT < 1.2 times the upper limit normal.

Participants must be enrolled in the study prior to 50 days (every effort will be made for prior to 28 days) after initial surgery performed for the combined purpose of diagnosis, staging and cytoreduction.

Participants with measurable and non-measurable disease are eligible. Participants with suboptimal disease are eligible. Participants may or may not have cancer-related symptoms.

Participants who have met the pre-entry requirements specified including serologic measurement of CA-125 as a baseline for subsequent determination of response using Rustin criteria.

Participants with a GOG Performance Status of 0, 1, or 2.

EXCLUSION CRITERIA:

Participants with a current diagnosis of epithelial ovarian tumor of low malignant potential (Borderline carcinomas) are not eligible. Participants with a prior diagnosis of a low malignant potential tumor that was surgically resected and who subsequently develop invasive adenocarcinoma are eligible, provided that they have not received prior chemotherapy for any ovarian tumor.

Germ cell tumors, sex cord-stromal tumors, carcinosarcomas, mixed mullerian tumors or carcinosarcomas, metastatic carcinomas from other sites to the ovary and low malignant potential tumors including so called micropapillary serous carcinomas are not eligible.
